Spin waves in graphene with Zeeman-type spin splitting

We present a computational study of spin waves in doped paramagnetic single-layer graphene with adjustable Zeeman-type band splitting. The spin waves are described using time-dependent spin-density-functional response theory, treating dynamical exchange-correlation effects within the Slater and Singwi-Tosi-Land-Sjolander approximations. We obtain spin-wave dispersions and spin stiffnesses as a function of doping and spin polarization, and discuss prospects for their experimental observation.
